The primary function of conditioner is to moisturize and detangle hair. Conditioners are formulated with ingredients that provide hydration to the hair, which helps to restore moisture that may have been lost due to environmental factors or heat styling. This hydration is crucial for maintaining hair's elasticity and softness.

Furthermore, conditioners often contain smoothing agents that help to reduce friction between hair strands. This makes it easier to comb or manage the hair, especially when it is wet and more prone to breakage. By detangling the hair, conditioners also help reduce the risk of damage that can occur from pulling on knots and tangles.

While some conditioners may have added ingredients that can enhance shine, their fundamental purpose is to provide moisture and manageability. Cleansing the scalp is primarily the role of shampoo, and adding color is typically a function of hair dye, not conditioner. Thus, the primary role of a conditioner centers around moisturizing and detangling, making hair more manageable and healthy.
